Summary

With a hydraulic height of 18 feet and a structural height of 22 feet, this dam has a storage capacity of 25.1 acre-feet, providing essential water resources for the surrounding area. The dam spans 450 feet in length and covers a surface area of 3.2 acres within a drainage area of 90 square miles.

Managed by the North Carolina Dam Safety Program, Olde Raleigh Dam #2 has been deemed to have a high hazard potential, necessitating regular inspections and maintenance to ensure its safety and structural integrity. The dam was last inspected in January 2020 and was assessed to be in satisfactory condition. Despite its high hazard potential, the dam meets regulatory guidelines and has an Emergency Action Plan (EAP) in place to address any potential risks or emergencies.

The presence of Olde Raleigh Dam #2 not only enhances the recreational opportunities in the area but also underscores the importance of proper dam management and safety measures. As climate change continues to impact water resources and infrastructure, dams like Olde Raleigh Dam #2 play a crucial role in providing sustainable water storage and recreational benefits for the community.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
